The random walk model used to describe gas diffusion can be treated as a binomial distribution similar to coin flips with a 50/50 chance that a particle will move in either the +x direction or the -x direction. If 10 steps are taken, how much more likely is it that the particle did not move (Δx=0 after 10 steps) compared to a situation where the particle moved 10 steps in the +x direction
